at the moment its tbdev .. simply because its a virgin source and by being this it inherients a lot of advantages of other sources and dispite what people say apart from the lack of current xhtml validity it really has no downsides unless ur an idiot to suggest the lack of pre-installed mods is a downside lol

if you want something thats xhtml valid i think btit is probably the next best thing .. ive used their source once before and was pretty impressed (although ive not really looked at any tstrike sources in ages so they may have got their act together).

however given that an incredible amount of people dont care for xhtml and most torrent sites dont even validate as transitional never mind strict (actually most sites still cant validate as html transitional or strict) i would suggest tbdev .. especially if u actually wanna learn something from your efforts :)
